Power banks with MTK-PE

Since USB 2.0 became a standard for charging port there are a couple of things happens. Devices got more and more battery capacity and that is why many fast charging protocols appear to overcome USB 2.0 default 2.5W (5v 0.5A). Those protocols were necessary to keep the same charging time with larger batteries. Some of those protocols were part of USB standard (like USB Battery Charging and USB Power Delivery) and some were not (like Apple 2.4A, Qualcomm QuickCharge, Mediatek PumpExpress+, and a lot of others).

Most chargers and power banks support only some of those fast charging protocols. So usually you will not get the fastest posible charging for all of your devices from the same source. For example power banks with Mediatek PumpExpress support is exceptionally rare devices. There are a number of power banks with Qualcomm Quick Charge or USB Power Delivery available, but not with Mediatek PE+. So below is three 10000 mAh power banks I found with MTK-PE support.

Power-Z KM001C

Power-Z KM001C is USB Type-C tester from ChargerLAB. Nice and slim. With OLED display. With good PC Software. Have similar features to KM001 and same PC Software.

Power-Z KM001C

The main issue of Power-Z devices is no good English translation for both firmware and PC Software, But anyway it still a useful tool. And PC Software is actually best in class. It is also an issue with Software updates. No single site you can search for the latest version. Link from app bottom line direct you to baidu folder with the previous release. But at least firmware automatical update is working.

D9 Air Quality Detector

This time OCRKJ D9-H. Which also can be found in some shops as unbranded LCD Digital Air Quality Monitor (AKA monllac, AgoHike, Robincure). Similar to OCRKJ K6-D from the previous review. It was bought for about 100$. Yet another portable device with 10 hours battery life and correct CO2 measurements.

D9 Air Quality detector

Pros

  • 3000 mAh battery ( 10 hours of battery life)
  • additional sensors (HCHO, VOC and PM2.5)
  • 16 different screens including trends
  • Active airflow with the relatively quiet fan
  • quality design and schematic inside (no glues, connectors, replaceable sensors)
  • good CO2 sensor inside – SenseAir S8 LP

Cons

  • slow charging – 8 hours (in operation mode)
  • no connectivity (Bluetooth, wi-fi, USB mass storage)
  • no ambient light sensor
  • unconfigurable high CO2 limits (GOOD is up to 1000 ppm)
  • wrong temperature and RH measurements (+3C, -10%RH)

It looks like relatively cheap SHT20 temperature and humidity sensor inside make it sort of a lottery if you will get correct measurements or not.

K6 Air Quality Detector

I was not expecting much ordering KKMOON K6 (and receiving actually OCRKJ K6). Which also known as CAFU K6. Because most of the portable air quality monitors I got before have at least one major issue with measurements (AiRead M3 – all measurements wrong, HT-501 – wrong temperature, AirRadio A6 – issues with CO2 measurement after outdoor use and wrong humidity measurements). AirVisual Node was the only exception that both portable and show correct numbers. But it just too big to put it in your pocket. So there was a long history of portable CO2 monitors with issues. And it was kind of a surprise that device I bought for 83$ is both portable and display correct numbers.

OCRKJ K6 Air Quality Detector

Pros

  • 3000 mAh battery ( 10 hours of battery life)
  • additional sensors (VOC and HCHO, PM2.5)
  • correct t, RH and CO2 measurements (not sure about other)
  • 16 different screens including trends
  • Active airflow with the relatively quiet fan
  • quality design and schematic inside (no glues, connectors, replaceable sensors)
  • good CO2 sensor inside – SenseAir S8 LP

Cons

  • slow charging – 8 hours (in operation mode)
  • no connectivity (Bluetooth, wi-fi, USB mass storage) – nothing
  • no ambient light sensor
  • unconfigurable high CO2 limits (GOOD is up to 1000 ppm)

Tqka Power Bank 10000 mAh

In the future fast charging might get some common ports and protocols. And it seems it will be type-c with USB Power Delivery in use in most cases. But for the moment it is several standards that provide more power than a standard USB port. Those standards are mostly not part of USB specification. And it is kind of unusual to have charger or power bank that support multiple fast charge protocols for different devices. That cause slower charging of some phones using charger or power bank designed for another. For example, at the moment most Qualcomm and Mediatek based Android smartphones have different fast charging standards. It took some time for me to find MTK-PE+QC3.0+Apple2.4 charger and power bank.

So the power bank is Tqka BA058

List of supported protocols

  1. Qualcomm Quick Charge 2.0 (QC2.0)
  2. Qualcomm Quick Charge 3.0 (QC3.0)
  3. Mediatek Pump Express 1.0 (MTK-PE)
  4. Mediatek Pump Express 2.0 (MTK-PE2.0)
  5. Huawei Fast Charge Protocol (FCP)
  6. Samsung Adaptive Fast Charging (AFC)
  7. USB Battery Charging 1.2 (BC2.1)
  8. Apple 2.4A

XINTEST HT-501 CO2 Meter

Portable CO2 meter and data logger with battery and good CO2 sensor inside.

Xintest HT-501

The only really wrong thing about this device is it always show temperature higher than it is for about 2°C (for example 28.0°C instead of 26.0°C) and it is not something related to wrong sensor placement.

Pros

  • Portable
  • 20h work from a battery
  • LCD Color zoning
  • Datalogger
  • Setup time and alarms from PC
  • Sensair S8 CO2 sensor

Cons

  • Incorrect temperature measurements
  • No time and date on the screen
  • 30 sec warmup time
